Danfoss valves Types TEX55/TEX12/TEX20/067B3250 Thermostatic expansion valves introduction
The TE 5 - TE 55 series expansion valve regulate the injection of refrigerant into evaporators.It controls the refrigerant flow based on the
superheat. The exchangeable power element is produced with the well known Danfoss laser welding technology for extended lifetime capability. The TE 5 - TE 55 series is available with a wide range of orifices which will cover a wide range of applications.
Applications:
- Air conditioning system
- Chiller
- Cold room
- Freezer
- Other refrigeration systems

Danfoss valves Types TEX55/TEX12/TEX20/067B3250 Thermostatic expansion valves Identification
The thermostatic element is fitted with a label (on top of the diaphragm).
The label holds information like valve type,evaporating temperature range, MOP point,refrigerant, max. working pressure PS / MWP and production date.
Production place and date (BE1315B) mean:
BE = Wuqing, China
13 = Week
15 = Year 2015
B = Tuesday
Orifice assembly for TE 5 – TE 55 The orifice assembly is marked on top of the spring cup, e.g. as shown in the figure.TE 12 = For valve type
06 = Orifice no.067B2709 = Orifice code no. for sales order 1315 = week 13, year 2015 Capillary tube tag for TE 5 – TE 55 The label gives the orifice size (06). A new label always accompanies a new orifice assembly.
